=-= shit , obviously that would be taught in schools and students must memorize it because its their national anthem...
but memorizing japanese songs are way difficult =-= i prolly fail my history class...

I'd rather have Borat's National Anthem than some shitty anime theme song :p
But if an anime theme song really became my national anthem, I'd probably flee the country after murdering the president if it's some shitty as anime theme song. I'll make a few exception. Love Gurren Lagann theme song, and Blood+ first theme.
